Judson's articles co-authored with others appeared in major scientific journals. One of Judson's research articles published in 1978[24] with B. Kishen Rao, S. S. Thakur and B. Juilus Divakar entitled The effects of a juvenile hormone analogue on the male reproductive organs of the red cotton bug, Dysdercus cingulatus (Heteroptera) appeared in the scientific journal Experientia (now Cellular and Molecular Life Sciences),[24]
He was much active among the academic fraternity in Hyderabad, India. In 2007, he co-organized a National Conference on Biodiversity Conversation and Human Wellbeing, which was conducted jointly by the Department of Zoology (OU) and Sálim Ali Centre for Ornithology and Natural History.[25] In 2008, he co-edited a compendium titled Biodiversity Conservation and Human Well-Being.[26] In 2009,[14] Judson convened a national symposium on the theme Implications of climate change on mosquito-borne diseases and its impact on public health[14] at Sir Ronald Ross Institute of Parasitology.[14]

Judson is also on the Advisory Board of Genesis Urban and Rural Development[38] under whose aegis a National Conference on emerging challenges and opportunities in Agriculture, Social, Plant, Environment, Cooperatives and Technology was held in 2016.[39]
Efforts by the members of the STBC-Baptist Church, Lallaguda resulted in creation of a social action initiative which was named Burden and Love for Economically and Socially Suppressed (BLESS)[27] in which Judson has been active and presently holds the position of Secretary.[27] Through the Church, he has been actively involved in promoting[40] food security[41] among those marginalized[8] dry land farmers of Telangana through System of Rice Intensification[28] in a few[28] mandals of Yadadri Bhuvanagiri district and Medchal-Malkajgiri district.
During the 2010s, he took up social action initiatives in Andhra Pradesh, Telangana and Odisha through the Canadian Baptist Ministries[42] in which he was a Field Staff[28] and Team member.[42] Judson is the present India representative[43] of European Baptist Mission International overseeing social action programmes[44] together with 16 partners in the country.[45]
